Privacy Policy
This policy covers wmichaelhsu.co. It is written to be read, not to cover anyone in legal fog. Last updated .
What we collect
Information you give us. If you submit a form (newsletter, waitlist, contact, booking), we collect what you type: typically your name, email address, and your message. We use it to do the thing you asked for, and for nothing else.
Numbers you run through our tools. Some of our sites offer calculators and tools (for example, runway and cash tools). Figures you enter are used to compute the result we show you. If a tool ever stores the figures you enter together with who you are, this policy will say so explicitly before that tool launches, and it will say how long we keep them.
Usage analytics. We measure page visits with PostHog. By default this is cookieless: nothing is stored on your device, and a return visit looks like a new visitor to us. If you click Accept on the cookie bar, we set 1 measurement cookie so we can understand repeat visits. If you click Reject, we stay cookieless. The site works identically either way.
What we do not do
We do not sell or rent your information. We do not run session recording. We do not currently use any advertising or retargeting pixels; if that ever changes, this policy will say so first and the pixel will only load for visitors who accepted.
Where your data lives
Like every modern site, we run on infrastructure providers who process data on our behalf: Vercel (hosting), Cloudflare (network and DNS), Supabase (database for form submissions), Resend (transactional email), PostHog (analytics), and Google Workspace (email). Form submissions also flow into our internal operations tooling so a human can respond.
How long we keep it
Form submissions are kept until you ask us to delete them. Analytics data is kept in aggregate.
Your choices
Email hi@xhack.co to ask what we hold about you, correct it, or have it deleted. We honor these requests regardless of where you live, which also covers the rights granted under GDPR and the California privacy laws. To change your cookie choice, clear this site's data in your browser and the cookie bar will ask again.
